Generally, the phases of constructing information systems are consisted of systems planning and selection, system analysis, system design, and system implementation and operation. These systems require many efforts and costs for additional development of modification requirements due to a frequent changes of business environments and business processes. Especially, inconsistencies between system design and system implementation usually happen during development steps because of the difficulties of program developments due to difficulties of capturing exact user requirements and frequent changes of user requirements. This paper proposes a scheme of implementing meta-data based applications for enterprises in order to reduce inconsistencies between system design and system implementation and to overcome limits of the existing coding-based development methods of applications which must use until disuse if they are developed once. Also, this paper presents a framework of repository system to systematically manage and utilize meta-data. The core concept of the proposed scheme makes outputs generated in the phases of system analysis and design into meta-data and is to easily develop and customize application programs using meta-data repository. Also, to show the applicability of the proposed scheme, it is applied to implement ERP system of 'H' automotive part manufacturer. As a result, the proposed scheme can gain improvements such as easiness and productivity of program development, easiness of maintenance, reusability of program components, etc.

As coming smart computing era, the government and leading telecommunication companies have actively supported the development of mobile applications. However, since it is processed apart from the characteristics of small businesses, policy problems and support ways have continuously been pointed out. In this study, we selected priority of support project for the activation of the mobile application development, then proposed support ways for the success of small development business. Firstly, we researched the mobile business literatures, support projects and policy trends of the Korean government, academia and private sector. Next, we developed the activation model for small development business by synthesizing of support projects, literatures and expert group interviews. Based on this model, we selected priority of support projects according to AHP (Analytic Hierarchy Process) analysis results. In conclusion, we categorize the five support ways for the activation of mobile application development. We are expecting that these support ways will be useful to the development of effective policies and selection of detail tasks for the support of small business or developers.

In this study, we propose a method to improve the guideline for accessibility of mobile applications based on the results of manual evaluation of 8 mobile online shopping applications which are widely used in Korea. 13 items of mobile online shopping application were found to have low compliance rate, and 5 items such as response time control were observed and there was no corresponding items. In the current mobile application accessibility guidelines, it is necessary to delete the check items that are not relevant or meaningless, and to provide additional logical items such as logical ordering and form creation, and to improve the accessibility of mobile applications, The government should make efforts to develop and disseminate the development guide, and to resolve the digital devides.

본 논문에서는 모바일 애플리케이션의 사용자 잔존율 향상을 위한 방안으로써 내러티브 모션을 기반한 온보딩을 제안한다. 모바일 기술의 발전과 새로운 미디어에 대응하는 디지털콘텐츠 애플리케이션에 대한 관심이 증가하고 있는 가운데 사용자에게 외면받아 사라지는 애플리케이션의 증가가 가속화되고 있다. 이에 따라 사용자의 긍정적 경험 제공을 위한 사용성 향상 연구는 빠르게 진행되고 있으나 애플리케이션의 첫인상과 지속적인 사용을 결정하는 온보딩에 대한 연구는 아직 미비하다. 경쟁이 가속화 될수록 보다 효과적인 사용자경험을 제공하기 위한 온보딩 개발의 중요성은 증대되어 갈 것이며, 결국 온보딩 개발의 핵심 쟁점은 사용자의 긍정적인 인지적 반응과 태도를 이끌어낼 수 있는 요인인 모션이 될 것으로 예측된다. 따라서 본 논문에서는 모바일 온보드에서 제공되는 애플리케이션의 다양한 특성을 표현하기 위한 요인으로서 내러티브 모션을 제시하고 애플리케이션 지속사용 여부에 영향을 미치는 요인을 도출하여 둘의 상관관계를 실증적으로 분석함으로써 앞으로 등장할 새로운 서비스 및 플랫폼의 애플리케이션 개발 필요한 모션요소를 도출하고자 한다.

스마트폰 사용자의 폭발적 증가와 함께 모바일 애플리케이션 시장에 대한 관심도 크게 증가하고 있다. 더불어 애플리케이션의 보안 위협 역시 증가하고 있는데 각 모바일 애플리케이션 마켓에서는 이에 대한 대처방안 중 하나로 코드사이닝 기법을 활용하고 있다. 코드사이닝 기법을 이용하여 애플리케이션 및 개발자에 대해 인증을 받는 방식에는 각 모바일 마켓별로 다른 점이 존재한다. 그 종류로는 개발자가 생성한 공개키와 해당 애플리케이션을 애플에 전송하고 애플이 이에 대한 검증을 하여 마지막 서명을 부여하는 방식의 애플 앱스토어, 개발자가 키와 증명서를 이용해 스스로 애플리케이션에 대해 증명서를 발급하는 방식의 구글 안드로이드 마켓, RIM에 등록되어 있는 코드사이닝 키를 이용하여 애플리케이션을 제출하면 자동적으로 서명을 받을 수 있는 블랙베리 앱월드, 사전에 개발자가 자기 증명을 통해 아이디를 발급받고 애플리케이션을 테스트 하우스에 등록하여 검증 및 서명을 받는 노키아오비스토어 등이 있다. 이와 같이 개발자 및 애플리케이션을 인증 받는 방식이 각 마켓별로 차이가 있는데 이에 대한 자세한 분석과 그에 따른 보안 위협에 대한 안정성에 대해 분석해 보겠다.

Augmented reality applications offering location based service on smart phone require attention to users and new usability evaluation methods. The aim of this paper is to introduce new usability principles for application development and usability evaluation, and conduct expert evaluation on the augmented reality applications. We created a set of usability principles by analyzing characteristic of augmented reality applications, and conducted expert evaluation on three augmented reality applications primarily used by smart phone users. In expert evaluation and filtering procedure, we identified six usability problems that three applications have in common and the improvement guideline for the usability problems. The results of expert evaluation was verified by user test with a prototype that was developed using the guidelines. It is expect that the results of this study can be presented usability principles of the augmented reality application and a method of usability evaluation in the middle of new technology development process.

The abolition of WIPI installation duty makes domestic WIPI developers get a chance to enter into smartphone development environment. Specially, iPhone has a big possibility for a new game application market but traditional domestic WIPI developers have difficulties to get in because there are no standard game development methodology. Therefore, a method is necessary to develop iPhone game application effectively for traditional domestic WIPI developers. In this paper, we compare and analyze development methodology of WIPI and iPhone application and suggest a new methodology for iPhone application development with adaptation of WIPI architectures. Using this methodology, traditional domestic WIPI developers can develop iPhone game applications with ease.

In this paper, we research on the personal information protection system in smart-phone based on mobile environment. This paper proposes the enhanced personal location privacy mechanism in location-based service environment of a smart phone operating system(iOS, Android) for the relevant regulations on location-based protection and utilization. Also, the result verified that possibility on a self-control mechanism of the personal information protection system's subject in the window platform throughout the experiment. Therefore, this study have drew a method that user positively can cope with a protection of personal location information by having a user's self-control method in the system under development or done by illegal location-based service providers and illegal application developer.

Web applications based on J2EE($Java^{TM}$ 2 Platform, Enterprise Edition) were occurred for solution to overcome the limitations in time and space that the former applications had. Recently, lots of solutions using frameworks are being suggested to develope applications more quickly and efficiently. In this paper, we propose the template for several processes and types, which should be taken in presentation layer of web applications. This idea was based on the fact that web applications developers can concentrate on their specific tasks with independent manner in layered architecture. This template is XML-typed document that shows information about presentation layer of Web applications, which the user wants to compose. This template is inputted to the code generator. After then, the code generator generates skeleton code in presentation layer automatically after parsing information of XML documents. It means that we can develope Web applications more efficiently, by constructing skeleton code which inherits from hot spot classes of framework. Using this template and code generator, developer can develop Web applications with little practice and also is easy to cooperate with other developers to develop them just in time with distributing the standard development process.
